RELATED APPLICATION

The present application claims priority to PCT Application PCT/CN2017/093854 filed on Jul. 21, 2017, which claims priority to Chinese Patent Application No. 201610590964.5, entitled “USER MANAGEMENT METHOD AND APPARATUS OF HYBRID CLOUD,” filed with the Patent Office of China on Jul. 22, 2016. The two applications are incorporated by reference in their entirety.

FIELD OF THE TECHNOLOGY

The present disclosure relates to the field of computer technologies, and in particular, to a user management method and apparatus for a hybrid cloud.

BACKGROUND OF THE DISCLOSURE

A public cloud is a cloud architecture that is provided by a third party for use by the public or by many business groups. The public cloud architecture provides cloud resources on a network, and all users having user permissions may use the resources as needed. High efficiency, low costs, and usage on demand are prominent advantages of the public cloud. However, the public cloud is also faced with problems, such as it lacks security guarantees required by certain enterprise or personal/business data. A private cloud is built at the center of data owned by an enterprise or an organization, or is built by a cloud service provider according to user demand. Except the owner, other users cannot use the private cloud. This can ensure integrity and security of data in a private cloud.

The private cloud computing environment is mainly oriented to enterprise users. Considering the security requirements, enterprises are more willing to deposit data in a private cloud, but they also want to benefit from the computing resources of the public cloud. In this case, a hybrid cloud architecture emerges. An existing hybrid cloud usually combines at least two private clouds and at least one public cloud.

However, cloud platforms in a hybrid cloud often have different user management methods, and the existing hybrid cloud lacks a solution to uniformly manage user data and user permissions in the hybrid cloud.

SUMMARY

According to a third aspect, an embodiment of the present application provides a user management apparatus of a hybrid cloud. The apparatus may include a transceiver, a processor, and a storage medium. The storage medium stores computer instructions. When the processor executes the computer instructions, the processor is configured to: obtain user data in a role-based access control RBAC system; determine, according to a historical record, historical user data that has been distributed to a cloud platform in the hybrid cloud; and obtain incremental data of the user data relative to the historical user data, wherein the transceiver is configured to send the incremental data to the cloud platform in the hybrid cloud.

DESCRIPTION OF EMBODIMENTS

Referring to FIG. 1, FIG. 1 is a schematic flowchart of an embodiment of a user management method of a hybrid cloud according to the present application. As shown in FIG. 1, the user management method of a hybrid cloud includes the following steps.

101: Obtain user data in a role-based access control (RBAC) system.

In this embodiment, an RBAC system is introduced to consistently manage users, roles, and permissions in a hybrid cloud platform. The RBAC system is a system for managing user data. In the RBAC system, the users, roles, and permissions are used as basic management elements. A user may be an entity that can independently access data or may be an entity that can be presented by data. A role is a job or position in an organization or a task. A permission is an operation allowed to be performed on one or more objects. In the RBAC system, a user may be authorized to own multiple roles, a role may be associated with at least one user, one role may be associated with at least one permission, and one permission may be associated with at least one role. A basic idea of the RBAC system is that a permission authorized to a user is determined by a role of the user. In the RBAC system, a permission is associated with a role, the role is associated with a user, and the user is not directly associated with the permission.

As shown in FIG. 2, FIG. 2 is a schematic structural diagram of an embodiment of a hybrid cloud and an RBAC system according to the present application. The hybrid cloud includes at least two cloud platforms, and the cloud platform may be a private cloud platform and/or a public cloud platform. At least some cloud platforms in the hybrid cloud respectively belong to different cloud architecture types. For example, as shown in FIG. 2, the hybrid cloud may include two private cloud platforms and one public cloud platform. The two private cloud platforms may be respectively private cloud platforms of an OpenStack type and a VMWare type. The hybrid cloud may further include a management platform and an application programming interface (API). The management platform may be configured to consistently manage cloud platforms in the hybrid cloud. The management platform of the hybrid cloud may include a database, a processor, and the like. The API of the hybrid cloud may be an access interface that is externally provided by the hybrid cloud and that is related to a user. The API may be mainly oriented to platform users, and the interface may be an interface through which the hybrid cloud as a platform externally provides services. When a user accesses the interface, the difference between lower-level cloud platforms is transparent to the user.

The RBAC system may include the API. An operation may be performed on resources within the RBAC system by using the API.

The API of the hybrid cloud may generate a new user data in the RBAC system by using a receiving operation. The RBAC system may consistently manage the user data. In this embodiment, the user data may include at least one piece of data, and each piece of data may include operation content and an operation object. For example, the hybrid cloud may add a new user in the RBAC system by using a receiving operation, and allocate a role to the user. The operation content in corresponding data may be newly added data, and an operation object may be the user and the corresponding role.

Often generating the user data in the RBAC system is not performed within a time period, but rather this task often takes place continuously. Therefore, the management platform of the hybrid cloud needs to periodically obtain the user data from the RBAC system. The periodically obtaining the user data refers to obtaining the user data every preset time period, or obtaining the data at a preset time point, or obtaining the user data when an instruction is received. This is not limited herein.

102: Determine, according to a historical record, historical user data that have been distributed to a cloud platform in the hybrid cloud.

The management platform in the hybrid cloud needs to distribute the user data obtained from the RBAC system to the cloud platforms. Specifically, the management platform stores in a local database the user data that were previously obtained from the RBAC system and that have been successfully distributed to the cloud platforms. Each time the user data are sent to the cloud platforms, the management platform also marks data that is successfully sent, to indicate that the piece of data has been sent to the cloud platforms. In this embodiment, the historical record includes a mark for data that is successfully sent.

103: Obtain incremental data of the user data relative to the historical user data.

After the management platform of the hybrid cloud obtains all the user data from the RBAC system, because at least a part of the user data has been sent to the cloud platforms, to avoid repeatedly sending data, the management platform compares all the user data obtained from the RBAC system with the historical user data recorded in the historical records to select the incremental data, that is, data that is not sent to the cloud platforms, from all the user data. The incremental data are stored in the local database.

104: Send the incremental data to the cloud platform in the hybrid cloud.

After selecting the incremental data, the management platform of the hybrid cloud sends the incremental data to the cloud platforms in the hybrid cloud, so that the user data in the cloud platforms are kept consistent, thereby facilitating the operations of the management platform.

Specifically, a database is set up in the management platform, and the database stores configuration information of the cloud platforms. The configuration information may include an Internet Protocol (IP) address between networks of the API, ports, user authentication information, and the like, that are provided by the cloud platform. The management platform sends the incremental data to the cloud platforms according to configuration information of the cloud platforms.

The method shown in FIG. 1 may be performed by the management platform of the hybrid cloud. The management platform may include one or more processors.

In this embodiment, the user data are periodically obtained from the RBAC system, and the user data are compared with user data that are locally stored in the hybrid cloud and that have been sent to the cloud platforms of the hybrid cloud, to determine the incremental data. Then the incremental data are sent to all the cloud platforms in the hybrid cloud. In this way, the user data of the cloud platforms in the hybrid cloud can be made to be uniformly distributed. In addition, because the user data of the cloud platform all come from the RBAC system, a permission of a user is associated with a role of the user in the RBAC system, and consistent permission management can be performed on the user data of the cloud platforms in the hybrid cloud by using the RBAC system.

In some embodiments, because the types of the cloud platforms in the hybrid cloud are usually different, the types of access interfaces provided by the cloud platforms may also be different. Therefore, in one embodiment, as shown in FIG. 3, the sending the incremental data to the cloud platform in the hybrid cloud may include the following steps.

1041: Traverse cloud platforms of the hybrid cloud.

The incremental data needs to be synchronized to each cloud platform in the hybrid cloud. After the incremental data are obtained, all the cloud platforms in the hybrid cloud are traversed. The incremental data needs to be sent to each traversed cloud platform. In this way, it can be ensured that the hybrid cloud consistently manages user permissions of all the cloud platforms.

1042: Adjust an access interface of each of the cloud platforms.

After traversing of the cloud platforms is completed, because the cloud platforms provide different interfaces of users, roles, and permissions, an access interface of each cloud platform needs to be adjusted.

1043: Send the incremental data to each of the cloud platforms.

After adaption of interfaces of the cloud platforms is completed, the incremental data are sent to the cloud platforms by using the adapted interfaces.

Specifically, in one embodiment, the access interfaces of the cloud platforms in the hybrid cloud are adjusted by using a preset adapter. The preset adapter may be associated with a standard adaptee interface; the incremental data are sent to the access interface of the cloud platform by using the preset adapter. A specific adaptee type of the standard adaptee interface is the access interface of each cloud platform in the hybrid cloud.

An adapter, a standard adaptee interface, and a specific adapter type in this embodiment are described below by using user interfaces as an example. For roles and permissions, refer to descriptions of the user interfaces.

In one embodiment, the adapter is specifically UserAdapter, and is a type for the management platform in the hybrid cloud to call. The adapter UserAdapter is associated with a standard adaptee interface IUserAdaptee and provides operation methods such as Create, Update, Get, and Delete. A corresponding operation method of a specific implementation type of IUserAdaptee is called in each operation method. For example, a specific instance object of IUserAdaptee is a cloud platform AWSPrivateCloudAdaptee, and a Create operation method of the cloud platform AWSPrivateCloudAdaptee is specifically performed in a Create operation method of the adapter UserAdapter. A design advantage of adapter-type UserAdapter is that all provided methods are consistent for upper-layer user callings, the difference in interfaces between specific lower-level cloud platforms are shielded from the user, and specific lower-level clouds are accessed by associating specific adaptee types.

A standard adaptee interface IUserAdaptee is a standard interface designed for access interfaces of all the cloud platforms in the hybrid cloud when the management platform performs encapsulation. IUserAdaptee provides standard operations and parameters to the access interfaces when encapsulating access interfaces of the cloud platforms in the hybrid cloud. The provided standard operations include general operations such as creation, deletion, update, and modification, and general parameters such as Name, Password, and Email are provided as well. A specific encapsulation type of each cloud platform in the hybrid cloud is implemented as the standard adaptee interface IUserAdaptee, and a specific adaptee type is turned into, for the adapter UserAdapter to associate, to call a method of different specific cloud platforms by using consistent interfaces.

Specific adapter types implemented as the standard adaptee interface are, for example, AWSPrivateCloudUserAdaptee, OpenStackPrivateCloudUserAdaptee, and QQCloudUserAdaptee. AWSPrivateCloudUserAdaptee is a user interface in which a private cloud platform of an AWS type is encapsulated. OpenStackPrivateCloudUserAdaptee is a user interface in which a private cloud of an OpenStack type is encapsulated. QQCloudUserAdaptee is a user interface in which the Tencent Cloud is encapsulated.

FIG. 4 shows one embodiment of adaption of cloud platform interfaces.

If a standard interface method cannot satisfy access to all the cloud platforms in the hybrid cloud, a re-write specific method may also be supported. In addition, a standard adaptee interface further provides sufficient expansibility. When a new cloud platform is connected to the hybrid cloud, only the adaptee interface IUserAdaptee needs to be encapsulated into a specific adaptee type, and upper-layer call relationships remain the same.

As shown in FIG. 5, FIG. 5 is a schematic flowchart of another embodiment of a user management method of a hybrid cloud according to the present application. This embodiment is based on the embodiment shown in FIG. 1. After step 104 in the foregoing embodiment shown in FIG. 1, the user management method of a hybrid cloud in this embodiment of the present application further includes:

105: Obtain a sending result of each piece of data to the cloud platform in the incremental data.

When the management platform sends the incremental data to the cloud platform, the API of the cloud platform sends back a receiving result of each piece of data, and the management platform may determine a sending result of each piece of data to the cloud platform by using a feedback result.

106: Determine, according to the result, whether the incremental data are successfully sent to the cloud platform.

107: Record the data in the historical record when the data are successfully sent to the cloud platform.

For each piece of data in the incremental data, when the data are successfully sent to the cloud platform, a mark for the data are added in the historical record. In this way, it can be avoided that the piece of data are subsequently repeatedly sent to the cloud platform.

In some embodiments, when the data are sent to the cloud platform, a sending failure may occur. Therefore, the user management method of a hybrid cloud in this embodiment further includes:

108: Obtain failure information of the data when sending of the data to the cloud platform fails, the failure information including information for indicating the data and the cloud platform.

Specifically, for example, failure information of one piece of data may be as follows:

{ “Name”: “user1”, “ActionType”:“Create”, “AdapteeName”:“QQCloudAdapatee”, }

109: Add the failure information to a message queue.

110: Resend the data indicated by the failure information in the message queue to the cloud platform indicated by the failure information.

Specifically, failure information in the message queue may be processed by periodically executing a background Job. In some embodiments, there are multiple reasons for failure of sending of data to the cloud platform. For example, the reasons may be a network reason, or an internal error of a cloud platform interface, or other reasons. For failure of sending of data caused by some reasons, sending succeeds when the data are sent again; for failure of sending of data caused by the other reasons, sending still fails when the data are sent again. Therefore, in one embodiment, the failure information further includes an occurrence time of failure of sending of the data to the cloud platform. As shown in FIG. 6, FIG. 6 is a schematic flowchart of an embodiment of a sending failure processing method in this embodiment.

When the message queue is read, each piece of the failure information is parsed. Specifically, failure information shown below is used as an example.

{ “Name”: “user1”, “ActionType”:“Create”, “AdapteeName”:“QQCloudAdapatee”, “StartTime”:“2016-03-30 10:05:02.187” }

Values of Name, ActionType, AdapteeName, and StartTime fields shown in the foregoing structure may be extracted from the failure information, other information of User1 may be obtained from an RBAC user management system according to the value of the Name field, and that a user distribution operation is Create may be determined according to the value of the ActionType field. That a target cloud platform QQCloudAdapatee may be determined according to the value of the AdapteeName field. The occurrence time in the failure information may be obtained according to the value of the StartTime field, a current time is obtained, and whether a distance between the current time and the occurrence time is greater than a threshold may be determined. If yes, it indicates that the failure information is time out, that is, the failure information is not successfully sent after at least twice resending, and then a time-out notification may be sent. The time-out notification includes the failure information. Specifically, the time-out notification may be sent via an email, so that a manager may process the failure information. If the distance between the current time and the occurrence time is not greater than the threshold, other information of User1 obtained from the RBAC system may be resent to QQCloudAdapatee according to the failure information. If the information is successfully sent, the failure information may be deleted from the message queue. If not, the failure information may be reserved in the message queue and waits to be processed at a next period of the background Job.

The steps in the foregoing embodiments shown in FIG. 5 may be performed by the management platform of the hybrid cloud. The management platform may include one or more processors.
